\ sealing caps or, closures, and more particularly to means for feedin the sealingdisks of cork or similar material of the closures to the assembling devices of the machine;

In feeding sealing disks of cork or the like to assembling machines, many difiiculties havebeen experienced owing to the fact that, first, such disks vary inthcir thicknesses to some extent, second, they are very li ht in weight, and third, they are apt to taie a curved or bent shape when being prepared or treated before they are brought upon the assembling machine.

One of the objects of'the present invention is to provide a simple and efiicient feeding attachment which automatically delivers the sealing disks from a mass to an assembling machine without regard to their thicknesses,

weight and more or less curved shapes.

' of the invention is With these and other objects in view, which will more fully appear as the nature better understood, the same consists in the combination, arrangement and construction of parts hereinafter fully described, pointed out in the ap nded claims and illustrated in the accomp nying drawings, it being understood that many changes may be made in "the size and proportion of the several parts and details of construction within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

Two of the many possible embodiments of the invention are illustrated in the accompanying drawings, in which Figure 1 is a central vertical section taken through a hopper provided with a feed chute constructed in accordance with the present invention in its preferred form; Fi 2 is a plan view thereof; Fig. 3 is a rear =e eviction tached to .31, which being journaled in the sides 11 of the hopper.

section taken through a modified detail'of construction.

ofthe same; and Fig.4 is a central vertical Referring now more particularly to F' '1 to 3, inclusive, the numeral 10 indicates 'a hopper, comprising sides '11, a front wall '12 2 and an inclined base 13. In this base is formed an inclined guiding passage 14 of a width which is slightly larger than the diameter of a sealing disk, the bottom of this passage being formedby a resilient plate 15 which is attached by screws 16, or other- WlSe, to the baselt The passage 14 leads to a chute 17, which is located in front of the hopper, and the bottom of which-is formed by'the plate 15. The closed front end 18 of the chute 17 is curved, the radius of its curvature being somewhat larger than the radius of a sealing disk of the closure. It

will be observed from the drawings that the front end 18 of the chute is arranged substantially at right angles to the plane of the bottom 15 thereof, and as a continuation of said front portion is formed a tube 19, leading to the tra orting means, which conveys the sealing gisks one after the other to the assembling machine The upper end 20 of this tube is inclined, preferably, to the same degree as the front portion 18, and merges into a substantially vertical section 21, which extends to the transporting means above mentioned. U on the front end of the bottom 15 is'held a pin 22, which-is seated in an aperture 23 the latter being attached, preferably, to the tube 19. The bottom plate '15 is vibrated by any suitable means, for instance by a cam in a guide block 24,

25, which is fixedly attached to a spindle '26,

rotatably mounted in lugs 28, that are formed upon the sides 11 of the hopper.

Rotation is imparted to this cam, for instance, by means of a belt 29, running over a pulley 30, which is keyed or otherwise atthe spindle 26, and over a pulley is secured to a shaft 32, the latter Upon the 0 receiving morality of leaf springs 36, also corresponding in width to that o the passage 14. These leaf springs extend outward from the peripheral portion of the drum, their free hopper above and in alinement with the pas- If two ormore slide,

tom plate 15 toward the front 18 of the sage 14, rotates in the direction of thearrow indicated in Fig. 1 of the drawings, and is mounted relative to the bottom 15 of the passage 14 in such a manner that the free end of a spring,when in its nearest position with relation to the said'bottom, is arranged at a distance from the upper surface of the bottom plate15 which is equal to the thickness of a sealing disk plus the throw of the cam 25. Within the hopper isheld furthermore aninclined plane 40, which serves to direct the sealing disks intothe passage 14 and also toward the drum 35, this plane having a slot 41, through which the drum projects above the said plane. a

The operation of this devlce is as follows: A mass of disks is placed into the hopper and rotation imparted by the intermediary of the driving pulley 33 to the drum 35, and thus to the cam 25. The rotating drum 35 agitates the disks, turns them repeatedly over and causes those at the bottom to move down the base 13 of the hopper, where they find their way into the guiding passage 14. Those disks which roll or slide down the base of the hopper edgewise are caused to remain within the hopper by the springs 36 of the drum. Those disks, however, which come to lie with one of their faces upon the bottom of the said passage, are moved along said passage toward the drum by the vibrating motion imparted to the bottom plate 15.

come within the reach of the drum 35, the springs will hold back all with the exception of the lowermost one, which is caused to due'to the vibrating motion of the botchute 17, where it is lowered by gravity into the tube 19, by which it is conveyed to the assembling'machine. As soon as aspring 36 comes into contact with the upper edge of the slot 41 in the plane 40, it is forced by the said edge toward the periphery of the drum, its guide plate 37 being thereby lowered into the drum. As soon as a spring is disengaged from the said edge, it springs back into its normal position, the outward motion being limited by its stop 39. The drum serves a two-fold purpose, that is as an agitating means, and at the same time as a gate controlling the admission of the sealing disks into the chute. The pur pose of the cam 25 is to vibrate the bottom differs from t e disks on top of each other.

of the passage 14 and the chute 17 such vibrationcausmg the disks to move toward the tube 19 irrespective of their weight.

From the foregoing it will be observed that a variation in the thicknesses of the disks does in no way affect the efliciency of the apparatus, neither does the fact that some of the disks might be bent or curved owin to their preparatory treatment. The weig it of an individual disk does not enter into consideration inasmuch as the vibration of the bottom of the guiding passage and chute causes them to slide toward the tube 19, no matter what their weight be.

A modification of the invention is illustrated in Fi 4'of the drawings, which preferred form hereinabove described in that the bottom plate 15 is reciprocated instead of being oscillated or vibrated. The plate 15 moves within guides 42, which serve at the same time to keep said bot-tom plate upon the hopper. means for imparting reciprocating motion to the bottom plate includes a crank 43, which is attached to a spindle 44, the latter being driven by the intermediary of a pulley 45 and a belt 46 from the shaft 32 above described. To the crank is pivoted a link 47, the latter being fulcrumed at 48 to a lug 49, which is attached'to the bottom plate 15. Otherwise the construction and operation of the device is identical with the one shown in Figs. 1 to 3, inclusive, of the drawings, the reciprocating motion of the bottom plate in this instance serving the same purpose as of the bottom plate shown in the device above described.

What I claim is 1. In a device of the character described, the combination with a hopper adapted to recelve a mass of sealing disks of cork or the like having a discharge opening and an inclined passage leading to said opening, of a chute communicating with said passage, the bot-tom of said passage and said chute being formed by a movable plate, means for imparting a shaking motion to said'plate, a drum mounted above and in alinement with sa d passage, and a plurality of springs on said drum, said springs serving to permit only those disks to enter said chute which slide on one of their faces in said passage toward said chute and at the same time to agitate the mass of disks in said hopper.
